FTLF1323P1xTR: frequently asked questions
What is the Finisar FTLF1323P1xTR?
The FTLF1323P1xTR is a Finisar SFP transceiver for OC-3 SR-1/IR-1, STM S-1.1 (155M) at 155 Mb/s. Finisar is now part of Coherent Corp. (formerly II-VI), and the part number is unchanged. It is used for Fast/Gigabit Ethernet, SONET/SDH OC-3/OC-12, campus and access links, and legacy network upgrades.
What does the 'x' in FTLF1323P1xTR mean?
FTLF1323P1xTR is Finisar's family / ordering name. The 'x' is replaced by a code to make the exact orderable part number. For this family the codes are: B, W. See the variants table and tell us which one you need, or share your switch and link details and we will pick the right one.
What is the optical power budget of the FTLF1323P1xTR?
Per the Finisar family datasheet, the FTLF1323P1xTR transmits −15 to −8 dBm and has a receiver sensitivity of −28 dBm.
Does the FTLF1323P1xTR support DDM / digital diagnostics?
Yes. Built-in digital diagnostics over 2-wire serial. Your switch can read live temperature, voltage, laser bias and Tx/Rx power.
Which part numbers are in the FTLF1323P1xTR family?
Orderable variants include: FTLF1323P1BTR, FTLF1323P1WTR. Next Gen Networks supplies the exact variant you need in bulk with a GST invoice.
What is the maximum distance of the FTLF1323P1xTR?
The FTLF1323P1xTR is specified for up to 15km over SMF. Long-reach optics may need an attenuator on short links; we can advise based on your link loss.
Which fiber and connector does the FTLF1323P1xTR use?
The FTLF1323P1xTR works at 1310nm FP over SMF. Both ends of a link must use the same optical standard.
Will the FTLF1323P1xTR work in my Cisco, Juniper, Arista or HPE switch?
The FTLF1323P1xTR follows the SFP MSA, so it fits any matching port. It carries Finisar's own EEPROM programming; switches that check the module vendor may need a configuration setting or a vendor-branded optic. Send us your switch model and we confirm before dispatch.
What temperature range is the FTLF1323P1xTR rated for?
The FTLF1323P1xTR is an industrial-temperature part rated −40 to 85 °C. Industrial grade suits outdoor cabinets, telecom huts and plant floors.
What does the FTLF1323P1xTR part number mean?
The FTLF prefix marks Finisar's SFP / SFP28 / SFP56 family (incl. Fibre Channel). The I letter in the suffix usually marks the industrial temperature grade. The remaining characters identify the optical design and build variant.
Is your FTLF1323P1xTR genuine Finisar?
Yes. Next Gen Networks supplies original Finisar / Coherent modules, not third-party lookalikes or grey-market stock, and shares serial numbers on request.
What is the FTLF1323P1xTR price in India and how do I order?
The Finisar FTLF1323P1xTR price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in for a GST quote.
What power does the FTLF1323P1xTR need?
It runs from 3.10–3.50 V with power dissipation of < 700 mW typ.
